Dead fish

[bryonb03]

Looking for help. My reef tank is about 5 months old. Over the past few days I have lost 2 clowns, blue hippo, and a diamond watchman goby have all died. Brought my water to be tested and everything checked out within normal limits. I have lps, sps, and softies plus a bta. All are doing well. The only thing that has changed is the frozen shrimp that I feed. Is there any way the shrimp could be bad? Any thoughts would be great. I would like to figure this out before I add any more fish.

Died meaning???
Found floating?
Found being eaten by CUC?
Any spots?
Any unusual behaviour?

Any motte detail?

No unusual behavior really started hanging by the bottom of the tank and then swimming sideways. Then dead. No spots nothing unusual

White light photos and video of the remaining fish and quarantine details if any will help us out.

Where did you get the frozen shrimp?

Are they aquarium food or intended for human consumption?

Two possibilities:
1. If your Fish were not QT'd a Pathogen.
2. Low Oxygen.
Post a video of your tank and more detail about how/when your fish were acquired and any visible symptoms mostly breathing rate.

Not likely it's the food your feeding.

Okay so the hippo… was that a recent edition by chance??

LFS aquarium food

All fish from LFS and in the tank for 3-5 months

No. Been in the tank for 4 months.

Have you added any inverts lately?

Where the pieces large.
Fish can choke and go sideways at the bottom because of that.
If not could be a contaminated pack.

Ah. Was wondering if the tang brought something, those tend to always bring something it seems!

 

[bryonb03]

Nothing new added!!

If they were breathing hard, I would suspect low O2. Do you have any other tanks? If so, maybe cross contamination. A third thought is some sort of toxin that got into your tank and how deep is your sand bed and did it stirred up? Can you take a pic of your tank/setup? That would help?

Whats the tank size?
Do you test the water when the fish die?
Do you QT? Possible disease?
Possible low oxygen as someone above mentioned?
Aggression?

A tank picture will help answer a lot of questions.
